A TTOH/VE YS UNITED STATES PATENT OFFICE.

PHILIP BRASHER, F' NEW YORK, N. Y.

' To all' whom z't may concern:

V-Be' it known that I, PHILIP' BRASHEE, a `citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the vcounty and State of New York, have invented Improvements'in Protecting Objects from Wave Action, of which the following is a full, clear, and exact de- 1 scription.

This invention 'relates to improved means for protecting objects from v wave action,

andv more particularly for discharging air upwardly through the water for breaking up the waves, an object of the invention being to provide improved means for dlscharging from the apparatus sand or foreign matter which may accumulate therein.`

A further object is to improve upon the vconstruction disclosed in Patent Number 843926, granted to me February 12, 1907, for protecting objects from wave action.

With these and other objects in view the invention consists in certain novel features of construction, and combinations land arrangements of parts, as will beY more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a vertical sectional elevation or profile, showing means embodying my invention applied to the protection of a bulkhead.

Fig. 2 is an enlarged view in transverse section through the air discharge pipe.

Fig. 3 is a broken view in longitudinal section through the air discharge pipe.

1 represents an air discharge pipe which is submerged inthe water 2 and mounted on any suitable support 3 and located at any desired distance from the bulkhead or bank 4, and adapted to discharge air upwardly .through perforations' 5 in the top o the air It ispossible that in the use of the de-v vice ,sand may drift into and through the perforatlons 5 in the top of discharge pipe 1, ultlmately so filling the said air pipe as a valve or cock 8 in Specification of Letters Patent. Patented Sept. 27, 1921. 4 Application led September 11, 1920. Serial No. 409,682. l

lVith this idea in view, I provide in the bottom of the air discharge pipe 1 an air pipe 9 of relatively small diameter having relatively small perforations 10 in its bottom, said pipe 9 resting on the bottom of the pipe 1. The pipe 9 has a closed end 11, which closure may constitute an ordinary plug as indicated, or the pipe may be closed in any approved manner, and the end of discharge pipe l is also closed, a cap 12 being indicated for the purpose.

The inlet end of the pipe 1 is preferably connected by an elbow 13 with the vsupply pipe 7 and the relatively small pipe 9, which constitutes a clean-out pipe, has its inlet end extending through the elbow and any sand or other foreign matter.

The operation is asy follows: During the operation of the device, when air is being discharged through the perforations 5, 'no sand or'foreign matter can enter -said pipe 1, but whilethe apparatus is idle, it is possible that sand may drift in through the perforations 5 and ultimatel ll the pipe 1.

f this is true, as soon as t e air is turned on, it, due to the fact that it cannot pass through the pipe 1, will enter the inlet end of the pipe 9 and escape through the perforations 10 in the bottom of said pipe 9 and whirl upwardly through the pipe 1 and out of the perforations 5, thus 'carrying with it the sand which may have accumulated in the pipe 1.

The perforations 10 of pipe 9 are located in the bottom of said pipe 9 and against the lower'wall o-f'the pipe 1. In such position It is, of course, obvious that various modifications might be resorted to in the general structure which would carry out the same general idea of an additional or auxiliary air supply pipe which would function to blow the sand out of the main air discharge pipe, and While I have illustrated what I believe to be a preferred embodiment of this idea, it is obvious that various changes might be made in the general form and arrangement of the parts described' Without departing from the invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. An apparatus of the character stated, comprising a pair of perforated air discharge pipes,one pipe of appreciably smaller diameter than the other and located Within the other.

2. An ap-paratus of the character described, comprising an air discharge pipe having air outlets in its top, and a perforated air pipe of smaller diameter located in the discharge pipe.

3. An apparatus of the character described, comprising an air discharge pipe having air outlets in its top, and an air pipe of smaller diameter located in the discharge pipe and having perforations in its bottoni.

4. An apparatus of the character described, comprising an air discharge pipe having air outlets in its top, and an air pipe of smaller diameter located in the discharge pipe and having perforations in its bottom,

said perforated portion of the smaller pipe normally resting upon the bottom of the discharge pipe.

5. An apparatus of the character described, comprising an air discharge pipe having perforations in its top, an air supply pipe communicating .with said discharge pipe, an air pipe of smaller diameter than the discharge pipe resting upon the bottom of the discharge pipe and having perforations in its lower portion, and said smaller pipe having an inlet end projecting into the air su l 1 e.
